Mercedes VGS4NAG2 TCU / Conductor Plate Clone, Virginize (Renew) & VIN Programming Service 2014+ (FBS4)

MERCEDES VGS4NAG2 TCU / CONDUCTOR PLATE CLONE, VIRGINIZE (RENEW) & VIN PROGRAMMING SERVICE

Professional Mercedes VGS4NAG2 TCU Clone, Virginize (Renew) & VIN Programming Service

Replace your Mercedes-Benz VGS4NAG2 transmission TCU with a fully functional donor module using our specialized Mercedes VGS4NAG2 TCU clone service and Mercedes TCU VIN programming. This Mercedes VGS4NAG2 TCU clone service is intended for situations such as a replaced transmission, valve body, conductor plate, or TCU where the vehicle won’t start, drive, or shift properly out of park. We focus exclusively on Mercedes TCU cloning, virginizing, and renewing donor conductor plates — safe, professional, and plug-and-play, without cutting or physically modifying the donor module.

Note: This service is designed for newer Mercedes vehicles with FBS4 security system TCUs (2014 and newer). If your vehicle has an older TCU with the FBS3 security system, see the link at the bottom for the appropriate Mercedes TCU clone and VIN programming service.

Important: Original & Donor TCU Requirements

To provide accurate and safe Mercedes VGS4NAG2 TCU programming, we require two modules:

• Original TCU (faulty / bad) — used only as a data source. We extract VIN, adaptation values, and transmission calibration from this module for Mercedes TCU clone and programming.
• Donor TCU — must have the same part number as the original. This functional module will be programmed with the original TCU data and returned to you as a fully working Mercedes VGS4NAG2 TCU clone.

Our process involves reading all critical data from the original TCU and writing it to the donor TCU, including VIN programming, creating a fully functional plug-and-play replacement. No cutting, soldering, or damaging is ever required. This Mercedes TCU clone service ensures your donor TCU is fully compatible.

Common Transmission Problems Leading to TCU Replacement

Many Mercedes owners require our VGS4NAG2 TCU clone and programming service due to issues such as:

• Fault codes related to shifting errors or limp mode (specific VGS4NAG2 codes available on request)
• Unresponsive or faulty VGS4NAG2 TCU causing rough or erratic shifting
• Signal errors from internal speed sensors or selection range sensors
